IMPROVEMENT IN META'LLICSIDINGS FOR BUILDINGS.

Speciication forming part of Letters Patent N0. 209,329, dated October 29, 1878 application filed March 18, 1878.

lTo all 'whom fit may concern:

Beit known that I, MASON H. GRITTENDEN,

of St. Paul, in the county of Ramsey and State of siding.

My invention relates to sheetmetal sidin gs for buildings.

It has for its objects to produce a siding which shall be free from the usual buckling which occurs under the infiuence of atmospheric changes, and which shall at the same time be readily and securely fastened in position so as to effectually exclude all moisture and successfully shed the rain.

Previous to :my invention, it has been customary, in forming panels from sheet metal, to simply treat the ends or edges of the sheet to form laps or` joints, the surface between such edges forming a single panel, either plane or angular, but without any support intermediate of the edges, the only exception being the ordinary continuously-corrugated metal, which in nowise presents a panel appearance.

My invention consists in forming two or more Hat-faced panels from a single sheet by crimping the metal in V-shape form at suitable points between the edges or ends of the sheet, and in also forming V-shaped laps at the extremities of the sheet, so that when a series of formed sheets are laid upon a building the joints will form grooves similar to those between the panels of each sheet, and so that said joints and grooves will, by reason of the obliqueness of their sides, successfully` shed or turn the rain.

To form my improved siding, I take ordinary sheets of metal, preferably iron, and press them, by machinery,'into the form shown at Fig. l with the channels or grooves a, in a number of places between the edges, which are formed with lap-grooves a', similar to a. This leaves the raisedV panels lb b on each sheet, and when placed upon thebuilding, as shown at Figs. 2 and 3, with the edges lapped, air-spaces care left under each panel, and the metal depressed to form the grooves serves as `intermediate bearings or supports, through which the nails or other fastenings may pass, as well as at the joints or overlaps,

which latter, as well as the grooves, are oblique to a horizontal line, and hence all moisture or rain is successfully turned, and does not lie to penetrate or corrode the joints.

In forming the grooves a a the metal is bent on a curve, and hence each panel terminates in an arch, which gives great strength, and at the same time serves to stiffen the face of the panel.

What I claim as new, and desire to secure by Letters Patent, is

Metal sidings for .buildingshaving two or more panels formed in each'sheet by intermediate V-shaped depressions or grooves, and with V-shaped grooves at each edge of the sheet to form lap-joints, substantially as and for the purposes set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
